Abstract
Based on standard Umkehr inversion algorithm the ozone vertical profiles have been retrieved from the Dobson Umkehr observations of Beijing. The corrections are made for aerosols in the process of inversion and the retrieved results have been improved. By using the derived profiles the characteristics and trends of ozone vertical distributions of Beijing during 1990-2002 are studied. The results imply that the ozone concentrations between 10.3 and 23.5km were unusually low during the fall of 1992 and the spring of 1993 and at the same time the total ozone underwent a marked decline. During the period 1990-2002 the total ozone decreased slightly but the trends of change of ozone concentrations at different altitudes were different.
